IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 172,754, dated January25, 1876; application filed November 1, 1875.

To all whom it may concern:

Be it known that I, WILLIAM Lor'r, ot'Elmwood, in the county of Peoriaand State of Illinois, have invented a certain new and usefulImprovement in Pumps for raising water from deep wells; and do here bydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the annexed drawings making a part ofthis specification, in which like letters refer to like parts, and inwhich- Figure l is a perspective view. Fig. 2 represents the top view ofthe reservoir or box for holding the water at or about the middle of thewell.

This invention relates to a double-acting pump having the reservoir ortank attached by screw-bolts to a plate, A, made long enoughtransversely, so that its ends will bear upon the sides of the well, andthus give a firm and steady support to the reservoir connected with theupper and lower tubing of the pump about the middle of the well, theupper end of the lower tubing being let in the said plate and fastenedthereto by a strap-plate, B, and screw-bolts, the lower end of the uppertubing being properly secured to the bottom of the said reservoir, andits upper end connected directly with the main stock of the pump, havinga handle or lever, and provided with a spout, the said handle carryingdouble pistonrods provided with bucket-valves arranged to work in thesaid tubing; also, to peculiarly constructed bucket-valves made in twosec tions, the upper section being connected to the end of thepiston-rod and secured to the lower section by rods and screw-nuts, thesaid upper section having a stop, m, constructed downwardly from thecenter on the interior thereof to prevent the valve from coming out ofthe opening in which it works, in combination with an adjustable ring topermit the bucket to expand with the pressure of the water as it isbeing raised up 5 the object of the invention being to simplify theconstruction of this kind of a pump, so that it can be more efficientlyadapted for the purpose of raising water from deep wells, as will behereinafter more fully explained.

a represents the handle of the pump substantially connected with theupper or main tubing of the pump, as shown, and to which is attached thetwo pistons d and b.

0 represents the iron device securely fastened at the top part of theupper tubing of the pump, by which and the action of the le- Ver onepiston is forced down while the other is being raised up, therebypermitting one of the buckets connected at the lower end of thepiston-rods in the usual way to fill with water while the other is beingemptied. 0 represents the upper tubing or main stock of the pump. '5 and9 represent the buckets attached to the lower ends of the piston-rods band (I. f represents the reservoir for holding the water at the middleof the well, and connected with the lower tubing at its upper endsubstantially with bolts or screws, as shown in Fig. 2. It

represents the lower part of the tubing, which extends from thereservoir to the bottom of the well.

Fig. 3 represents the bucket attached to the piston-rods b and d. Thisis made in sections and connected with bolts 0 and b.'

B represents the shape of the upper section of the bucket. 01 representsthe piston-rod near the upper part of the bucket. O (1 represent theshape of the lower section of the bucket. e 0 represent the adjustablering, which is held in its place on the outside of the bucket by arecess in the same, permitting it to expand with the pressure of wateras it is raised up.

A represents the valve, with a stem which passes through the opening inthe lower part of the bucket, which is raised up as the bucket is forceddown, thereby permitting the water to pass through, and then going backto its place by the weight of the water as the buoketis being raised up.

Having thus described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is-- 1. In a double-acting pumphaving a main stock provided with a spout and pivotal handle or levercarrying the piston-rods provided with bucket-valves, the reservoir ortank f, connected with the upper and lower tubing h g by means of plateA, the upper end of lower tubing being fastened thereto bya strap-plate,

stop, m, to prevent the valve A" from coming out of the opening in whichit works, in combination with adjustable ringe, substantially as shownand set forth.

In' testimony thereof I hereunto set my hand and seal this 29th day ofOctober, 1875.
